# TransformersChartsAndPlotsAnalysis

Subclass of [**Task**](/tasks/task.md)**.** 

## Module: [implementation](/framework-structure.md#implementation).tasks

## Default predictor

This task uses [**TransformersGenerativeModel**](/predictors/transformers-predictors.md#transformersgenerativemodel) by default with this configuration:

{% code overflow="wrap" fullWidth="false" %}

```python
model = Pix2StructForConditionalGeneration.from_pretrained(
    "google/deplot"
)
predictor=TransformersGenerativeModel(
    TransformersModelConfig(
        model=model,
        kwargs={
            "max_new_tokens": 512
        }
    ),
    input_class=TransformersChartsAndPlotsModelInput,
    output_class=TransformersBasicOutput
)
```

{% endcode %}
